Chapter 16, Problem 2TY

In mice, the allele of the Igf2 gene that is inherited from the mother is never expressed in her offspring. This happens because the Igf 2 gene from the mother

  1. always undergoes a mutation that inactivates its function.
  2. is deleted during oogenesis.
  3. is deleted during embryonic development.
  4. is not transcribed in the somatic cells of her offspring.
  5. all of the above.

Glitazones reduce insulin resistance by binding to a transcription factor in adipocytes, thereby reducing thesecretion of fatty acids. Glitazones are taken orally (in pill form). Using pharmacokinetic modeling, deriveequations to describe how the concentration of glitazones varies in the plasma as a function of time. Yourequations should be of the form: dCglitazone /dt = something, or dMglitazone /dt = something. Your model shouldinclude three compartments: the gut, the plasma, and the fatty tissues. Make sure to include a diagram thatillustrates your thinking, state all assumptions, and define your variables. Do not solve the equations.
Case Study—Ella Review the case study and then answer Parts A through F. Ella has a family history of diabetes. She wants to follow a healthful eating pattern that can lower her risk for developing this condition. Her dietitian recommends a goal of 450 to 600 kcal per meal and advises Ella to follow the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates and the Dietary Guidelines for Americans 2015-2020, which recommend limiting added sugar. She also recommends that Ella choose whole grains rather than processed grains. Ella decides to pack a lunch to take to work every day. This morning she’s making a sandwich for her lunch.   Categories of Sandwich Options (Top of the screen) Breads Spreads Cheeses Vegetables Proteins Specific food items to select White Bread 6-inches Honey Mustard Provolone LettuceTomatoBell Peppers Turkey Part A - Reading Nutrition Facts Panels for Total Kilocalories   How many total kilocalories are in Ella’s sandwich?   _____…
